These two compounds form a mixture because they can not react with each other under normal conditions.
NaCl and SiO2 are chemical compounds.
h2otable salt (NaCl),table sugar ( C12 H22 O11) and sand (Sio2)
Ionic bonds in compounds such as NaCl and covalent bonds in say diamond (C) and quartz (SiO2)
It would be a mixture since the NaCl and SiO2 would remain distinct from one another.
Many compounds have lattice structures. A lattice is just a long repeated structure. This is evident in salts, such as NaCl, but can be present many other compounds. Other examples are Diamond, SiO2 (quartz), and ice.
Sand is a mixture of many different compounds, but the main component is Silicon dioxide, SiO2 .
By stronger, I am guessing you meant " stronger intermolecular forces ". Ionic compounds do not necessarily have stronger intermolecular forces than covalent compounds. For example, it is true that NaCl(an ionic compound) has strong electrostatic attractions while H2O(a covalent compound) has very weak London forces. However, SiO2 is a giant covalent compound, and has very strong covalent bonds between molecules, even stronger than the electrostatic forces of NaCl.
Some are and some are not. Some water soluble inorganic compounds include ammonia (NH3), sodium chloride (NaCl), and copper sulfate (CuSO4). Some water insoluble inorganic compounds include silicon dioxide (SiO2), calcium carbonate (CaCO3), and lead iodide (PbI2)
silicon oxide- SiO2
Quartz is primarily silicon dioxide (SiO2).
It is impossible to use a platform in this platform.
very few compounds of either metals or nonmetals are gasses at room temperature.for example lets look at the oxides of semiconductors:carbon - CO2, gassilicon - SiO2, solidgermanium - GeO2, solid
The most common molecule on earth is SiO2.
